I just got a new Betta yesterdat after not having one for quite some time. I also got him a new tank in which I put spring water, water conditioner, gravel, a java fern, and a few other decorations for him to toy around with. The water fluctuates between 72 and 74 but I want him to be warmer(or is he just fine?). Does anyone have any good suggestions on small heaters that would heat such a small tank effectively without overheating it? I don't want to cook the little guy, just make him extra cozy. :)

I would go get a bigger tank. Most people suggest at least having a betta in a 2 gallon. I have a 1.5 gallon tank that I have a heater for a ten gallon tank in it, and it works fine, but it's risky having a big heater heat a small tank. No, I don't have a betta in the 1.5 gallon tank. I have 18 platy fry in there until I can get a big storage container for them.

I actually can't get a new tank at this time. The 1.2 gallon tank I have right now is all I have and my betta is currently still in the small cup I bought him in. Which I don't like, however, I don't want to put him into the bigger tank without a source of heat. Which is why I asked for suggestions on good heaters to heat the small tank until I have the funds to get a new tank for him.

I think the hydor mini heater says it can heat a 1G but it only heats up the water to a couple degrees F. And even with that, you would have to make sure that it didn't cook your fish, so you'd have to have a thermometer in there.

I went out today and bought a Tetra Submersible Aquarium Heater from wal-mart because it claims to keep the water at 78 degrees, shut off when it reaches that temperature, then kick back in when the water deviates slightly from 78 degrees. It's been in there for about an hour now and my thermometer does read 77-78 and won't go any higher. Much much better than the 70 I found it at this morning when I woke up. Anyways, it seems to be working great and my betta is a happy camper. I hope it stays constant, I'll be watching closely.

Is the heater still working alright for you? I need to get one for my small tank at work and was wondering the same thing you were.

So i went out lastnight and got the same one from Wal-Mart. Now im going to install it today......did u put it in with your betta in the tank and let them warm up together or did you take your betta out let the water heat up and let your betta climatize in a baggie at the surface of the water? I would like to get the heater in today but dont wanna shock freddy. :)
